I wouldn't give up on the USB support quite yet. In another thread on
this mailing list, Stewart Morgan got it to work pretty well. I am
still waiting on more feedback from Jochen and Stewart so that we'll
get permanent Liebert support.

Regarding RS-232 support, you might want to experiment with the
"belkinunv" driver. I don't know if it will work, but knowing that
Liebert and Belkin use identical USB protocols, I wouldn't be
surprised if they used compatible serial protocols as well.
